setDaemonIdleTimeout()

Configure how long idle daemons remain active

Sets the idle timeout duration for daemon processes in daemon mode. Daemons that remain idle longer than this timeout are automatically closed to free up system resources.

Syntax

OpenComicAI.setDaemonIdleTimeout(timeout?: number): void

Parameters

timeout · number · default: "60000"

Idle timeout in milliseconds. Daemons inactive for this duration will be closed automatically.

Returns

void - This method does not return a value.

Behavior

• Daemons track their last usage time
• When a daemon is idle for longer than the timeout, it’s eligible for closure
• Automatic cleanup helps prevent memory leaks
• Setting a longer timeout keeps daemons alive for more reuse
• Setting a shorter timeout frees resources more quickly

Example

import OpenComicAI from '@opencomic/ai-bin';

// Set timeout to 2 minutes (120,000 milliseconds)
OpenComicAI.setDaemonIdleTimeout(120000);

// Set timeout to 30 seconds for aggressive cleanup
OpenComicAI.setDaemonIdleTimeout(30000);

// Daemons will automatically close after being idle
await OpenComicAI.upscale({
  input: 'image.jpg',
  output: 'upscaled.jpg',
  daemonMode: true
});

// Daemon stays alive for reuse within timeout window

Timeout considerations

Short timeout (10-30 seconds)

• Aggressive resource cleanup
• Less daemon reuse
• More startup overhead
• Better for sporadic processing

Medium timeout (60 seconds - default)

• Balanced approach
• Good daemon reuse
• Reasonable resource usage
• Suitable for most applications

Long timeout (2-5 minutes)

• Maximum daemon reuse
• Daemons stay in memory longer
• Less startup overhead
• Best for continuous processing
